Description
図1乃至図11を参照して第1実施形態について説明する。図1は、スナップボタンの概略的な断面図である。図2は、雌スナップの概略的な上面図及び断面図である。図3は、組立前の雌スナップの概略的な分解断面図である。図4は、雄スナップの概略的な上面図及び断面図である。図5は、図6に示す一点鎖線X5-X5における雌スナップの概略的な水平断面図であり、回転角度範囲の規制構造を示す。図6は、図5に示す一点鎖線X6-X6における雌スナップの概略的な部分断面図である。図7は、図1の一点鎖線X7-X7における弱スナップ状態の雌スナップの概略的な水平断面図である。図8は、図1の一点鎖線X7-X7における強スナップ状態の雌スナップの概略的な水平断面図である。図9は、雄及び雌スナップの嵌め合わせ過程を示す概略的な断面図である。図10は、雄及び雌スナップの嵌め合わせ過程を示す概略的な部分拡大断面図である。図11は、強スナップ状態のスナップボタンを示す概略的な断面図である。
図12を参照して第2実施形態について説明する。本実施形態においては、上述の実施形態とは異なり、リング体40の主面(上面又は下面)には、半径方向に延びる6つの溝41zが対称配置されている。これにより、リング体40の変形が促進され、保持力の増大を図ることができる。より詳細には、溝41zをリング体40の主面に設けることによって、被押圧部40mが缶体10の押圧部10mにより半径方向内側へと押圧されたとき、リング体40に変形が生じやすくなり、リング体40の開口P40の開口形状が簡易に変形する。例えば、開口P40の開口形状が、正円から楕円へと変形する。これにより、雌スナップ210の受入部P210が雄スナップ220のポスト105を保持する保持力を増大させることが可能になり、より十分な保持力の範囲を確保することができる。なお、本実施形態の場合にも、第1実施形態と同様の効果を得ることができる。
図13を参照して第3実施形態について説明する。本実施形態においては、上述の実施形態とは異なり、リング体40は、直径R40と直径R41の中間値である直径R42を有し、リング体40の被押圧部の突出量が、周方向において段階的に変化する。この場合、雌スナップ210の受入部P210が雄スナップ220のポスト105を保持する保持力を3段階とすることができ、これにより、保持力の微妙な調整が可能になる。なお、保持力の調整段数は3段階に限られるべきものではなく、3段階以上としても良い。本実施形態の場合にも、上述の実施形態と同様の効果を得ることができる。
図14を参照して第4実施形態について説明する。本実施形態においては、上述の実施形態とは異なり、リング体40が楕円状であり、同様に、缶体10(筒部12)も楕円状である。図14(a)乃至(c)に示すように、リング体40を反時計回りに30度、90度と段階的に回転させると、図14(a)に示すように缶体10に対して非接触であったリング体が、図14(b)に示すように缶体10(筒部12)に接触し、そして、図14(c)に示すように缶体10(筒部12)により挟み込まれる。図14(a)~(c)は、図13(a)~(c)に対応する。このような態様でリング体40の半径方向外側への変形を抑制する場合であっても、上述の実施形態と同様の効果を得ることができる。
図15乃至図19を参照して第5実施形態について説明する。本実施形態においては、上述の実施形態とは異なり、リング体40と回転体50を機能的/構造的に一体化した単一部材のリング回転体70を用いる。これにより、上述の実施形態と同様の効果に加えて、雌スナップ210の厚みを抑制することができ、また、部品点数も少なくすることができる。更に、本実施形態においては、上述の実施形態とは異なる構成の雌スナップ210及び雄スナップ220を用いる。この場合であっても、上述の実施形態と同様の効果を得ることができる。
図20及び図21を参照して第6実施形態について説明する。上述の実施形態では、固定部材(図1に示す缶体10、図15に示す下部取付保持枠60)に押圧部を設け、回転部材(図1に示すリング体40、図15に示すリング回転体70)に被押圧部を設ける。他方、本実施形態においては、回転部材に押圧部を設け、固定部材に被押圧部を設ける。このような場合であっても、上述の実施形態と同様の効果を得ることができる。
図22乃至図28を参照して第7実施形態について説明する。上述の実施形態では、周方向における押圧部と被押圧部の相対位置を任意に変更することができる。他方、本実施形態においては、雌スナップの製造時、周方向における押圧部と被押圧部の相対位置を設定/固定し、リング体の半径方向外側への変形が制限された強スナップタイプとリング体の半径方向外側への変形が制限されていない弱スナップタイプを別々に製造する。このような場合であっても、製造後における強弱調整機能が失われるに留まり、上述の実施形態と同様の効果を得ることができる。なお、本実施形態においては、上述の実施形態における強弱調整機能が、スナップタイプの選定により置き換えられている、とも言える。強スナップタイプでは、雌スナップ210と雄スナップ220の連結/連結解除に、より強い力が必要になる。本実施形態では、上述の実施形態とは異なる構成の雌スナップ210を採用する。このような場合であっても、上述の実施形態で説明した利点が失われることはない。
図29乃至図32を参照して第8実施形態について説明する。上述の実施形態では、リング体が単一の環状の弾性材料から構成されていた。他方、本実施形態では、リング体を複数の部材に分割し、リング体の変形がリング体を構成する各部材の配置間隔の変更により達成される。この場合においても、リング体は、バネ等の弾性部材の活用により、元形状へ復帰可能であり、上述の実施形態と同様の効果を得ることができる。リング体の構成部材に金属材を活用すれば、その強度を高め、スナップボタンの耐久性を向上させることができる。本実施形態では、リング体を2つに分割し、両者を弾性部材の板バネで連結している。しかしながら、リング体の分割数は任意であり、3以上に分割しても良い。分割した各部分を弾性的に接続する具体的態様は任意であり、必ずしも、後述の板バネに限定されるものではない。
図33乃至図39を参照して第9実施形態について説明する。図33は、雌スナップの概略的な上面図及び断面図であり、図33の紙面上部に上面図を示し、図33の紙面下部に同図に示した上面図のX33-X33に沿う断面図を示す。図34は、雌スナップのリング体の概略的な上面図及び断面図であり、図34の紙面上部に上面図を示し、図34の紙面下部に同図に示した上面図のX34-X34に沿う断面図を示す。図35は、雌スナップの板バネの概略的な斜視図である。図36は、図33の断面図の一点鎖線X36-X36における非ロック状態の雌スナップの概略的な水平断面図であり、(a)においてU字部の合体状態を模式的に示し、(b)においてU字部の分離状態を模式的に示す。図37は、スナップボタンの概略的な断面図であり、雌スナップが非ロック状態にある。図38は、図33の断面図の一点鎖線X36-X36におけるロック状態の雌スナップの概略的な水平断面図である。図39は、図38の一点鎖線X39-X39におけるロック状態の雌スナップの概略的な垂直断面図である。
図40乃至図42を参照して第10実施形態について説明する。図40は、雌スナップの概略的な水平断面図である。図41は、雌スナップのリング体の概略的な上面図及び断面図であり、図41の紙面上部に上面図を示し、図42の紙面下部に同図に示した上面図のX41-X41に沿う断面図を示す。図42は、雌スナップの概略的な水平断面図であり、同図(a)において非ロック状態を示し、同図(b)においてロック状態を示す。本実施形態においては、第9実施形態とは異なり、回転体50に対して板バネ49を係合しない代わりに、リング体40に対して板バネ49を連行するための連行構造を設ける。このような場合であっても上述の実施形態と同様の効果を得ることができる。
図43及び図44を参照して第11実施形態について説明する。図43は、雌スナップの概略的な水平断面図であり、(a)においてU字部の合体状態を模式的に示し、(b)においてU字部の分離状態を模式的に示す。図44は、雌スナップの概略的な水平断面図であり、ロック状態の雌スナップを示す。本実施形態においては、第9及び第10実施形態とは異なり、回転体50/リング体40の回動に関わらず、板バネ49p、49qが変位しない。このような場合であっても、上述の実施形態と同様の効果を得ることができる。
図45を参照して第12実施形態について説明する。図12は、雌スナップに含まれるリング体の概略的な水平断面図であり、各U字部に対して板バネが一体的に設けられた場合を示す。本実施形態では、第9乃至第11実施形態とは異なり、U字部45p、45qに対して板バネ49p、49qが一体的に設けられている。このような場合であっても第9乃至第11実施形態と同様の効果を得ることができる。U字部と板バネの一体性は、例えば、U字部を樹脂製とし、板バネを金属製とし、両者をインサート成形にて一体成形することにより達成可能であるが、これに限られるべきものではない。
